6-Rib 3.50" Supercharger Pulley for 1996-1999 Mustang Cobra
The Paxton Superchargers 6-Rib 3.50" Supercharger Drive Pulley (PN 4PFK036-350) is a precision-machined pulley engineered specifically for 1996-1999 Ford Mustang Cobra applications equipped with compatible Paxton centrifugal supercharger systems. Designed for the modular 4.6L DOHC Cobra engine, this pulley provides accurate blower speed control and dependable belt engagement.
With a 3.50-inch diameter and 6-rib belt profile, this pulley is commonly used to fine-tune boost levels - often reducing blower speed slightly compared to smaller pulleys for improved safety margins, drivability, or pump-gas setups.
Boost Control & Drive Accuracy
Supercharger pulley diameter directly affects impeller speed and manifold boost. The 3.50" size offers a balanced option for Cobra owners seeking reliable performance while maintaining belt traction and minimizing slip at higher RPM.
Paxton pulleys are manufactured to tight tolerances to ensure smooth, vibration-free operation, helping extend belt life and reduce stress on supercharger bearings.
Designed for Paxton Supercharger Systems
This pulley is intended for use with Paxton centrifugal superchargers installed on 1996-1999 Mustang Cobra vehicles. Proper pulley selection should always account for supporting modifications such as fuel system capacity, charge cooling, engine internals, and ECU calibration.
